Thevenin’s theorem with solved examples this theorem was presented by a french engineer m.l. thevenin in 1893. through this theorem, complicated networks (especially electronic networks) can be solved very quickly and easily. this theorem can be described as follows;. Example 1 determine the current i in the network by using thevenin's theore. solution: step 1. the thevenin's equivalent circuit is. step 2: to find vth: from the given circuit disconnect rl = 10 Ω. step 3: to calculate rth: from the above circuit, kill the sources. the resultant circuit is. Example 2: calculate thevenin's voltage and thevenin's resistance. solution : to calculate thevenin's voltage (vth) : here the open circuit voltage is the same as that of the voltage across the resistor of resistance 7 Ω. after replacing the source with their internal impedance the thevenin's impedance is.
